ANTIFRICTION-BEARING.

Specication of Letters Patent.

Patented June 1, 1915.

Application led November 10, 1908. Serial No. 461,967.

which the following is a specification,refer-v ence being had therein tthe accompanying drawings.

My invention relates to an anti-friction bearing. One objectI of theinvention is to provide `yielding means at one side of each of theLantifriction deyices of the bearing to absorb the thrst movementthereofand maintain theantiffriction elements in pera-tive position.

Another object of the-invention is to provide means'to take the endthrust of the anti-friction devices.

The invention also consists in the combi-- nation or combinations ofparts hereinafter described'and set forth in the claims.

The invention may be adapted to all forms of bearings that'are providedwith antifric tion devices. As one illustration of 'such ladaptation, Ihave for convenience illustrated inthe drawings and described herein,the invention as applied to a vehicle wheel, but it is not tobe intendedby such drawings and description thatthe invention is limited to such adevice.

Referring to the'drawings, Figure 1 is an elevation, partlyv in section,of a bearing embodying my invention. Fig. 2 is a section on the line 2-2, Fig. 1'. Figs. 3, 4 and 5 are detail views.

In the drawings, 1 indicatesan axle'l 2 indicates a casing or cagesurrounding the axle 1 and comprising an annular base 2 and a series ofbars 2, preferably formed integral with one surface thereof and arrangedapart at intervals to form spacing devices.

2" indicates a ring which is preferably provided at the opposite endofthe casing. The ring 2" may be formed integral with the .bars 2B.

3 indicates the lanti-friction devices preferably comprisingr rollersmounted between the bars 2 around the axle 1. 'lhese rollers engage withand form the bearing surfaces between the axlel 1 and the hub 4, of aVwheel 5. The hub 4 preferably comprises a bushing E"4 surrounding thecasing 2 and forming a confining wall for the rollers in rollers 3 backmeans preferably comprise a spring strip-ofA metal 6" having laterallybent portions 6 near its opposite ends that engagewiththe` adjacentroller. As illustrated in the drawings, there is a yielding device 6'between one side of each roller 3 and 'an-adjoining spacing bar 2, andthat all of the yielding devices are arranged on the same vsideofztherollers. This eonstructionof bearing.- permits limited movements betweentheA hub4 and axle 1 in lateral directions, which movements are causedby abnormal forces acting on the wheel and operate to bind the rollers 3at o ne end against the Aspacing bars2, or'

other parts of. the bearing.. When these!A forces cease, the yieldingdevices 6 press the into normal osition again so that the hub 4 will runtrue on the axle 1.

8 indicate yieldingor resilient means arranged between the opposite endsof the rollers and the rings 2, 2b. For convenience, these yieldingmeans are formed by bending over the ends of the strips 6 so that they`engage the rings 2, 2", at 8n and the ends of the rollers at 8. Theyielding means 8, operate to take the end thrust of the rollers. Thesprings 6 may be riveted or otherwise secured to the bars 2, asindicated at 6".

9 indicates a thrust bearing formed in the end of the axle.

10 indicates acone carried by the hub case I 4a to engage with thebearing 9. A 11 indicates a screw for securing the case rnut l'is largeenough in diameter to overlap the end of thehushing 4 and thus hold itand the casing iii position. The case 4,

carrying the spokes and wheel rim, is then slipped over the end of thenl Xle and bushing 4 and secured to the latter by the screw 1,1

What I claim is 1. In a bearing, the combination of an axle, a series ofrollers, and means for spacing said rollers relatively to each other,said means includinga ring arranged at oneend of said roller-sandloosely mounted on said aXle and a plurality ,of laterally yieldabledevices extending longitudinally .of said rollers and supported fromsaid ring and each arranged, to engage the `outside .periphery of anadjacent roller.

2. In a bearing, the combination of a cage Comprising a ring and aseries of bars, a series of rollers mounted between the bars, and aspring strip arranged between. each roller and a-bar.

3." In 4a bearing, the combination of a cage comprising a ring and aseries oi? bars, a

.series of rollers mounted between the bars,

and a Spring strip arranged between each roller and one side of eachbar.

4. AIn a bearing, the combination ofa cage comprising a .ring and aseries of bars,a A

series of rollers` mounted between the bars,

vand a spring strip arranged between each roller and one side of eachbarand all of thegstrips being arranged on the same side y. thereof.

5. In ,a bearing, the combination of a series 'of rollers, bars forspacing the rollers apart,and.a spring strip arranged between eachroller and an adjoining bar.

f 6. In a bearing, the combination of a g series of rollers, bars forspacing the rollers apart, a spring strip arranged .between each rollerand an adjoining bar and each strip thrust movementof the roller.

7. In a bearing, the combination With two members, one of which rotates.relative to the other, of a frame comprising an end wall and a seriesof spacersrigidly supported relatively to each other by said end wall, aseries of anti-friction devices for the said members arranged betweenthe spacers and movable bodily in endwise and lateral directions, andyielding means arranged between one side of each device and the face ofan adjacent spacer and between one end of each device Vand said endWall, and operfriction devices.

8. A nen7 article of manufacture fory a bearing havinganti-friction-devices, comprisinga spring strip arranged to engage thecircumferential surfaceof a device and provided with yieldable endmembers arranged to engage the opposite ends of the device. 1
